Rocket’s red glare

I must reply to Fabiano Micoli for unreasonably attacking modern climate science. Over the 600 million years to which Micoli refers, how many have been fit for human habitation? The important question is: what has happened to CO2 levels and the global temperature over the last 200 years? Both CO2 and temperature are going up. The CO2 molecule reflects infrared (heat) back to the earth. NASA has intensively studied and documented this, and anyone who flies in an airplane trusts their life to NASA science. If you do not trust NASA, keep both feet on the ground.
